Martin (smallbutfine) created a thread asking about a multiple ADAT interface. I've been thinking about something similar, but I didn't want to hijack his thread.
I'm trying to find something with multiple simultaneous digital i/o's, AES/EBU or SPDIF. Something like the RME HDSPe AES, except externally connected (maybe USB) instead of PCI Express and maybe not so expensive. Just two simultaneous digital i/o's would be fine.
Unfortunately, my RME UFX has one AES/EBU and one optical SPDIF, but only one can be used at a time. I think the Apollo has only one RCA SPDIF.
Does anyone know of a USB device with two simultaneous digital i/o's? It doesn't matter if it has anything else. My goal is to be able to record two Burl (or other high-quality) stereo A/D's, use my Dangerous D/A for monitoring, and use my Burl D/A and and another high-quality A/D for an analog chain during mixdown.

Well, the RME Fireface UC is USB and can be configured for 2x SPDIF i/o (1x RCA, 1x TOSLINK)...
But not cheap at all if you do not need anything else in this box.... :-(

Thank you for finding that, Martin. I stupidly assumed that the UC was a simplified version of the UCX which was a simplified version of the UFX.
The only thing the UC is missing for me is the Totalmix FX. Not as good as UAD's FX obviously, but more than adequate to inspire singing performances with no latency.
However, because of your suggestion, I took a serious look at the RME UCX, and it has two simultaneous digital i/o's as well as Totalmix FX. So I'm going to investigate the possibility of "downgrading" my UFX to a UCX.
Thank you again!

Point out that if you get a Apogee or the 2192, you can use SMUX ADAT with your current interface for your analog IO loop. The RME should allow ADAT and SPDIF simultaneously--my Multiface does.
Really not a lot of options....I think you'll get into a clocking issue at some point with all these different converters. I'm not sure how much advantage they'd have versus just clocking internally to the main unit. I think this converter hype is all blown out of proportion. If you're going to be doing a ton of ADA loops to analog gear, you just need to buy an interface you're comfortable with the conversion on. I mean...the difference is...tangible with the very best...but, it's also tangible to have your whole system running off a single internal clock.
I would check the RME before moving--the Multiface is NOT that way. Yes--it has both ports...and you can configure the optical as SDPIF instead of ADAT, but they're not completely independent--it mirrors the other spdif or disables it or something...there was some feature that made it not actually useable as a second SPDIF. Not saying the UC is the same way...but, I had been told it could be used as dual SPDIF, too....nope. I'd want to hear from someone who has actually hooked two independent SPDIF ins and outs and used them simultaneously.

Hi popmann, thanks for your comments. Here's a line out of the UC manual: "The Fireface UC has two SPDIF inputs and outputs. Coaxial and optical can be used simultaneously, with different audio signals.". The UCX manual has the same. My UFX manual specifically states this can't be done, as does your Multiface manual: "In SPDIF mode, identical signals are available at both the optical and the coaxial output. An obvious use for this would be to connect two devices, i.e. using the HDSP as a splitter".
I can get by with what I have, I don't need a ton of ADA loops, but I wouldn't mind having one. I don't like the fact that I can't even switch between using the AES input for my Burl and using the Spdif for my Kemper without having to go into the RME control software and making a change. It's inconvenient. But worse, with only one digital output, I can't use one for my Dangerous Source for monitoring and one for a high-quality DA for an analog chain.
Thank you for pointing out that the 2192 has an ADAT interface, I didn't realize that, and it made me investigate further. Another possibility would be something like the RME ADI-4 format convertor. The ADI-4 with a UCX might be a perfect combination for me, with lots of digital i/o's and RME FX, for not much more than the price of a UFX.
